The lack of any joy with the MSF signal has got me thinking about radio electronics. I connect a wire to CH1 on my Xprotolabs Oscilloscope because I remember getting random signals once before.
Here's watch I picked up.
Now while this is a divergence from the Z80 theme, I think its well worth looking into so improve my electronics knowledge as this is part if the journey.
So I learnt recently about transistors, and how they can amplify a signal. So lets amplify this and see what we can make of it...
